That would be a sweet machine man, MONARCH CNC!! A real nice 10EE is a thing of beauty for sure. Once I get this Cincinnati Arrow 500 retrofit completed and hopefully making me some cash I would like to find a nice older Cincinnati slant bed or maybe a CHNC Harding's lathe to retrofit to complement my mill. I have decent 12x36 manual lathe here but would really like to have a nice CNC lathe. Gotta be a nice capacity and still be small enough to run on single phase power like the Arrow. Maybe 7.5-10
